A few about Wyatt Earp and Lotta Crabtree...

Fun Fact I: In our collection, HLS Library has a deposition of Wyatt Earp (1848-1929), an American lawman and subsequent legend of the "Wild West," perhaps best known for his involvement in the gunfight at the O.K. Corral. The deposition references well-known Old West figures such as Doc Holliday and Wyatt's brother, deputy U.S. Marshal Virgil Earp.

Earp was deposed on April 7, 1925, in connection with the Estate of Lotta M. Crabtree (1870-1924), a wealthy American actress. After her death, multiple parties unsuccessfully contested her will, claiming to be her rightful heirs. Earp was deposed due to his acquaintance in Tombstone, AZ, in the early 1880s with her brother Jack Crabtree. You can view the entire 329-page deposition online at https://bit.ly/hlslearp [citation 1].

Fun Fact II: Why was it filed in Massachusetts Probate Court? Because, at the time of Lotta Crabtree's death, she lived in Boston, in the Hotel Brewster (at the corner of Washington and Boylston Streets), which she had purchased in 1909, shortly after it opened [citation 2]. Various obituaries called her one of the richest women in America.

Just days after her death, a probate case was filed with several people laying claim to a portion of her “approximately $4,000,000” [1924 value] fortune, which she left to various charities. Today, her estate would be worth about $78 million [citation 3].

Fun Fact III: Lotta Crabtree also owned land in the Squantum section of the City of Quincy, where several roads are still named for her or her family, including Ashworth, Livesey, Sonoma, and Crabtree [citation 4]. According to the Quincy Historical Society, “all four streets sit squarely upon Squantum property formerly owned by Charlotte [Lotta] Crabtree...

• Ashworth Rd: Appears to have originally been laid out as part of Newland St., but marshland made completion impractical. Compare this with the adjacent Lansdowne, Essex, Deerfield, and Heath Streets.
• Crabtree Rd: Broadly speaking, this road follows the path from Charlotte Crabtree's main house to several other secondary houses, outbuildings, etc. on her property.
• Livesey Rd: More or less follows the path of a driveway, road, or other cleared area along the eastern edge of the property nearest the main house.
• Sonoma Rd: More or less follows the path of a driveway, road, or other cleared area along the northern edge of the property nearest the main house” [citation 5].

We extend special thanks to the for its research assistance.

We hope you found these facts as fun as we did. You never know where your research will take you when you start looking in our collection.

In September, HLS Library kicked off this year’s Book Talk series with “Constitutionalism and Its Discontents” (2026). Authors Mark Tushnet and Bojan Bugarič were joined by panelists Vlad Perju and Ryan Doerfler to discuss the book, which Tushnet said is a follow up to their previous book “Power to the People: Constitutionalism in the Age of Populism” (2021).

Tushnet described the book as having three parts: (1) discontents with constitutionalism as such; (2) discontents with programmatic constitutionalism; and (3) discontents with the efforts to remedy or get out of the situation of democratic decline or backsliding. After the discussion, panelists took questions from students.

Book Talks are held in collaboration with the Office of HLS Dean John Goldberg and can be viewed in their entirety at www.youtube.com/harvardlawschool.

Fun Fact Friday: At some point over the last 100 years, this small key opened the door to the world's largest academic law library. The key was one of several items on display at a recent pop-up exhibit (you never know what we'll display next).

Fun Fact Friday: Did you know some medieval legal books were pocket-sized and served as portable “working” books? For example, this mini Magna Carta (Great Charter) in the HLS Library collection is approximately 4 inches tall and 3 inches wide.

This early 14th century copy is difficult to open, but you can see the first page has an illuminated initial of King Edward II, who reigned from 1307 to 1327, and shows him enthroned before a striking gold and blue checkered background.

First written in 1215, Magna Carta was added to the Statute Rolls in 1297, making it part of England’s statutory law. The Law Library owns nearly 30 early manuscript copies of Magna Carta, all of which have been digitized.

This document was recently on display at one of our pop-up exhibits. You never know what we’ll feature next.
